When LOCAL_STRIP_MODULE := keep_symbols is set, then the normal strip rules
will be modified so that only the .debug_* sections are removed. The original
symbol table is left alone.
This allows the compilation of certain libraries so that libbacktrace library
can provide meaningful names to functions.

arm and arm64 have distinct headers, but mips and mip64, and x86 and x86_64
use headers that work for both widths. So where arm/arm64 need to handle the
second architecture case specially, all we need to do for the others is
hard-code the name. (x86_64.mk already hard-codes x86; we need to change
x86.mk for the case where we're building the 32-bit binaries for a mixed
system. mips64.mk doesn't exist yet, but when it does, it'll hard-code
just plain "mips" too.)

This should never have been on the default include path.
The NDK statically links its own libthread_db, so I'm removing
bionic's unused copy from devices.

This is the first step to build 32-bit libraries in a 64-bit product.
It will work like this:
1) In the product's BoardConfig.mk, define:
TARGET_2ND_ARCH, TARGET_2ND_ARCH_VARIANT, TARGET_2ND_CPU_VARIANT.
The build system uses those variables to set up an additional compiler
environment for the second arch.
2) When parsing Android.mks, the build system sets up rules to build a
module for both the 1st arch and the 2nd arch, unless it's explicitly
asked to skip so.
Android.mk will be adapted if there is additional rule of generating
source files.
The build system will accept arch-specific LOCAL_ variables, such as
LOCAL_CFLAGS_arm, LOCAL_CFLAGS_armv7-a-neon, LOCAL_CFLAGS_cortex-a15,
LOCAL_CFLAGS_aarch64 etc. Modules use such variables to set up build for
various archs at the same time.
3) Install binary of the 2nd arch by adding "<module_name>:32" to
PRODUCT_PACKAGES. All 2nd-arch libraries linked in by "<module_name>:32"
will be installed automatically.

For global declaration of FDO profile generation and usage,
we need to link PRIVATE_TARGET_FDO_LIB (libgcov.a by default)
prior to linking shared libraries.
TARGET_FDO_LIB is set if feedback directed optimizations
are in use, so we do not need to worry about consistent size
increases from this change.

Enable _FORTIFY_SOURCE=2 for x86 and MIPS.
Currently, this change is a no-op, as Android's libc doesn't
support _FORTIFY_SOURCE > 1, yet.

Add -D_FORTIFY_SOURCE=1 to the default cflags
Update build rule for executable with PRIVATE_ALL_WHOLE_STATIC_LIBRARIES
Use single dash version of -print-whatever
compile everything with relro / bind_now
Enable NX protections

Error "cc1plus: error: unrecognized command line option
‘-mfloat-abi=softfp’" is much more confusing than
"...gcc: No such file or directory".
Also we don't build in Windows/Cygwin any more so we don't need the old
trick.

Otherwise the previously exported value will be sticky and the value
defined in the TARGET makefile is ignored.

Use "LOCAL_SDK_VERSION := <number>" to build against the NDK when you
include $(BUILD_EXECUTABLE).

GCC 4.6 --version can return 4.6.x-google but also simply 4.6
as of https://android-review.googlesource.com/#/c/42028.
Add more pattern to detect it.
